1906. Serial No. 305,141.

To all whom it may concern:

. Be it known that I, GOTTFRIED STUPPAR., a citizen of the UnitedStates, residing at South Chicago, in the county of Cook and State ofIllinois, have invented a new and useful Improvement in a Device forMending Pipes, of which the following is.a specification. 1

The object of this invention is to provide a ready'means for stopping aleak ina Water or steam pipe or in a hose. I

The invention consists of a suitable pack,- ing material anda pliablemetal covering adapted to hold the packing material in place, and twohard-metal bars to which the ends of the pliable metal strip aresecured, together with means for securing the metal bars to each other.

In the accompanying drawings, Figure 1 is a perspective view showing theapplication of my invention. Fig. 2 is a cross-section through'a pipeshowing an end elevation, my device applied thereto. Fig. 3 is'a similarview in whichthe end portions of the. pliable metal strip are foldedabout the hardmetal bars. Fig. 4 is a perspective view showing the metalstrip and bars preparatory to placing the same upon a pipe. Fig. 5 is adetail outline perspective showing a portion of the strip and of onebar, and showing the strip Wound around the bar.

In the drawings, A represents the pi e to be re aired, and Urepresents astrip of phable meta such as tin-and B is packing material of anydesired kind. D represents two metal bars, and I prefer to have the samemade of steel In applying the device the packinglB is placed around thepipe so as to.

cover t e break, and the end portions of the strip C are soldered to thebars D, as indicated at E. The bars D are wrapped within the endportions of the strip 0, so as to enfold the bars more or less. Suitableperforations are then drilledthrou h the tin and the bars and the metalstrip (i is carried around the I pipe A and over the packing material B.

Bolts F are then passed through the perforations, each bolt passingthrough each of the bars 1), and nuts Fare screwed on the bolts. Thisdraws the bars and ends of the strip together and tightly binds thestrip 0 and the packing material around the pipe.

It Wlll be obvious that by wrapping the ends of the strip C more or lessabout the bars D the length of the strip between the bars will beregulated so that it will be the right length for pipes of variousdiameters, and the smaller the pipe the more the end portions of thestrip will be wrapped about the bars D.

- It will also be obvious that if the bars D were omitted and the boltsF and nuts F were applied only to the metal strip C the strip would beliable to tear out, or it would Having thus fully described myinvention,

what I claim, and desire to secure by Letters Patent, is

1. A pi e-mending device comprising a strip of p iable metal, metal barsermanently secured to the ends of sai strip adapted to be enfoldedtherein to adjust the length of the strip to pipes of various diameters,and means for locking said bars together, as set forth.

2. A pipe-mending device comprising a air of metal bars, a strip ofpliable metal rmly secured to and adapted to be wrapped around said barsto regulate the length of the stri to pipes of various diameters, asuitable paclfing material, and means for locking the bars, as setforth.
